Endoscopic ultrasound is the method of choice to diagnose and exclude small pancreatic neoplasia. Due to the high spatial resolution provided by EUS small cystic and necrotic areas are easily identified. Typical endosonographic features of pNETs are hypoechogenicity and necrotic areas in B‑mode and arterial hyperenhancement after injection of ultrasound contrast agents.
